Check out https://github.com/mixonic/ranked-model.git branch master then:

bundle bundle exec appraisal install bundle exec appraisal rails-5-2 rake

   The tests should run green and return.

@brendon thanks for opening the issue. Have you been able to reproduce this locally? Looking at the Travis runs you linked to, I don't see a hang, but I see that there is an exception raised after rspec finishes running the specs and reports the results. Is there another command running at the end? Could you perhaps run with RUBYOPT=-d to show what exceptions are being raised?

[brendon]

Hi @brixen, It hangs locally and needs to be killed. I think travis might just be killing it after a timeout?

Here's my local run with RUBYOPT=-d: https://gist.github.com/brendon/56943e8bdcd8ca9c215742304a83dcc4

You can see at the end where I'm killing it. I'm not sure about all the noise at the start :)

@brendon thanks again for opening the issue. It should be fixed in 387c488798d8b911f160d36278710474e526d73f. I'll tag a release as soon as CI finishes.

[brendon]

Thanks @brixen :) Glad you were able to figure that one out :D

Just on a side note, in my quest to upgrade the test suite for ranked-model I discovered that both pg and mysql2 have pulled support and CI for Rubinius. They're both actually broken on Rubinius on their current latest releases. I'm not sure if you're aware of this, but I wanted to let you know just in case. It seems like these two gems would be good to keep compatible with Rubinius if Rails support is important going forward.

Thanks @brendon, I appreciate the heads up.
